JOHN HILTON, OF WOOD SIDE, BEACONSFIELD, ENGLAND.

APPARATUS FOR SOWING SEEDS.

Specification of Letters Patent. Patented Sept. 23, 1919.

Application filed July 9, 1919. Serial No. 309,770.

To all whom it may concern:

Be it known that I, JOHN HILTON, a subject of the King of Great Britain and Ireland, residing at Wood Side, Beaconsfield, Bucks, England, have invented certain new and useful Improvements in Apparatus for Sowing Seeds, of which the following is a specification.

This invention relates to improved apparatus whereby vegetable, cereal, flower and other seeds are delivered in measured quantities and sown at any desired distance apart.

This invention is of that class employing a disk having one or more holes, or cavities sunk into its periphery, each of a size to receive one or more of the seeds to be sown.

In the accompanying drawings Figure 1 is an elevation of the improvedapparatus and Fig. 2 a plan. Fig. 2 shows the action of a scraper attachment which may be used in conjunction with the apparatus. Fig. 3 is a section through the seed container, Fig. 4 aside view and Fig. 5 a plan of the same. Fig. 6 is an elevation of an alternative arrangement. The disk a with cavities 1) (Figs. 3, 1, and 5) may be removably secured to the axle of a wheel, 0 (Figs. 1 and 2) so that when the wheel is run over the ground the disk rotates (as shown in Fig. 1) or the disk may be in a separate axle driven from the axle of the wheel 0 which runs on the round (as shown in Fig. 6).

The seed to be sown is carried in a detachable container d (Figs. 1, 2, 3, at, 5, and 6) the lower end of which has an aperture 6 (Figs. 3 and 5) through which seeds can be introduced or discharged. This open lower end of the container rests upon the periphery of the disk, as shown in Fig. 3. So long as the disk is not rotated the seeds in the container are prevented from escaping by the periphery of the disk, which closes the aperture but when the wheel is run over the ground and the disk in consequence rotates each cavity in the disk is filled in turn with one or more seeds,and carries these seeds under a forward lip of the container. As the rotation proceeds the seeds fall by gravit-y or are thrown by centrifugal force out of the cavity. In Fig. 3 cavity 1) is shown filled with seeds; l/Vhen disk at is rotated in the direction of the arrow these seeds will be carried forward under the lip 7 and be drawn or dropped from the cavity.

The container rests upon the disk in a vertical or inclined position, and is held in position by a spring. In Figs. 1, .2 and 6, this spring is shown in the form of a bent wire or strip 9 having a pointed end detachably engaging an indentation h (Figs. 1, 3 and 5) in the upper end of the container, but it may take any convenient form and may engage with any part of the container. In order to provide for wear and for adjustment of degree of pressure this spring is adjustably bolted to the handle or shaft 0. The attachment and detachment of the container is effected by pushing the container under or from the spring. When free of the spring the container may he slid around the disk until its aperture is uppermost and then drawn away for emptying or charging.

In order that the portion of the container which bears upon the periphery of the disk may not rock or jump upon its seating a guide is provided in the form of a slotted projection 2' (Figs. 3 and 4) from the container spanning the axle of the disk.

In order to facilitate the emptying and filling of the container the lower portion of the container with its aperture, lips and slotted guide, may be made detachable from the rest. In that case the lower portion may be removed when emptying or filling is necessary. This detachable portion is seen clearly in Fig. 3.

The quantity of seed delivered by each cavity is determined by the size of the cavity in relation to the size of the seed. The distance between the two deposits of seed will vary with the spacing of the indentations around the periphery of the disk, and in order that a disk appropriate to the desired distance and measure maybe fitted, provision is made for the ready detachment and attachment of disks to the axle. In Figs. 1 and 1 this provision is shown in the form of a nut which holds the disk against a shoulderof the axle. \Vhore the disk is on an axle other than the axle of the groundwheel the spacing of the seeds can also be varied by driving the disk by change-speed toothed or chain or other gearing from the axle of the ground-wheel. In Fig. 6 the disk is shown driven by chain 70 and its speed can be altered by changing one or both of chain wheels 2'.

The seed carried out from under the lip of the container is thrown or dropped forward, preferably into a trough m (Figs. 1 and 6) down which it slides to the ground.

seed fail from any cause] The curved portion of the trough is shaped so as to allow a disk to be removed or attached without need for moving or removing the trough. The troughis painted or otherwise made vivid so that the seeds may be seen as they slide along it, or is made of resonant material such as thin sheet metal, so that the impact of the-seeds can be heard. By one or other of these tell-tale devices the operator is warned at once should the container run empty or the delivery of the Two or more disks each with its container or all drawn from one container, may be employed on the same axle; two or more drills being thereb sown at the same time.

,The axle of the groiiuid wheel rotates in a journal or journals formed in a frame or fork to which are secured the seat trough and. other attachments. and which. also.

carries in the case of a geared seed-disk,

means for opening the drill in front of the seed'trough and closing it after the seed is deposited. The manner of 'accomplishlng this is shownin Figs. 1, 2 and-6. The lower end of the seed trough is carried down be low the ground l'evel and being'pressed into the ground as the apparatusis pushed for ward, opens in he soil a drill intowhich the seeds'slide, and the disturbed soil'is pushed back into the drill, thereby'covering the seeds,Q-,by scraper g. .-In' order toj avoid of the drill whence it can bepushed back by the single inclined scraper Q (this-action is ing. r

shown in Fig. 2) or may be a thin blade set slantwise to push the earth to one side of the drill as it gets through the ground.

The apparatus may also carry an adjustable side-trailing bar of any customary pattern for marking the position of the next drill.
